By default, Android no longer compiles code using it's custom linker script /build/core/armelf.xsc. However, this causes problems for libc. Certain programs linked using older versions of GOLD expect libc.so to export __exidx_start and __exidx_end. Removing the custom linker script causes libc.so not to export those symbols. For now, continue using the old linker script, until we can figure out a better solution. Change-Id: Iaf002afd63a58b848818da24e5a4525620dc4d74
